2 Claims.

This invention relates to screens as used in preventing insects from entering a building when the windows are raised.

An object of the .invention is to provide a screen detachably engaged with the window sash in such manner' as to be raised and lowered with it.

A further feature is in the provision of run ways for the side edges of the screen, attached to the window frame, preventing the passage of insects and also maintaining the screen in operative po-v sition irrespective of air currents.

Another purpose is to produce a screenwhich is automatically coiled upon a roller withl the descent lof the sash and,whi ch maintains'the` screen at all times under tension. 5

These and other like objects are accomplished by the novel construction and combination of parts hereinafter described and shown in the annexedV drawings, forming a material part of this disclosure, and in which:-

Figure 1 is a front elevational view of aI conven- -tional type of dwelling house window showing an application of the invention.

Figure 2 is a longitudinal sectional view taken on line 2-2 of Figure 1.

Figure 3 is a similar sectional view taken online 3--3 of Figure 1.

Figure 4 is a transverse sectional view taken on line L-I of Figure 1, drawn to an enlarged scale. Figure 5 is a partial side elevational, partial sectional view, the section being taken on line 5-5 of Figure 7.

Figure 6 isa sectional view taken on line 8 5 of Figure'ii.

Figure 'I is a transverse'sectional view taken on line 1--1 of Figure 5.

. Figure 8 is a similar sectional view taken on line l-l of Figure 5. Y

Figure 9 is a longitudinal sectional view taken through the spring actuated roll on which the screen is coiled.

Figure 10 is a front elevational view of a window, similar to Figure l, but showing the screenv at the top of the window.

A conventional window' frame is designated generally by the numeral I5 carrying upper andy lower sashes i6|1 respectively.

Mounted on the sill or lower -element of the window frame is a box-like casing i8 ush with the front of the frame i5.

Disposed over the end portions of the permanent cover of the casing are plates 20 having slots 2i to receive screws 22 and raised vertically from these plaies are uprights 23 forming the outer (c1. 15s-39) I' walls of narrow chambers 24 having rear walls .2,5 and closed at their outer edges as shown.

Movable in these chambers are the narrow ends 28 of a cross bar 21 while at their opposite, outerv ends are blocks 28.

Fixed on the bar 21 are clips 30 adapted to en gage the lower members of the Iinner sash, while their inner portions 3i extend conveniently to be grasped' by the hand in raising or lowering the sash. i

Secured in the underside of the bar 21 is the upper edge of a woven wire screen 32. The lower .edge of the' screen is attached to a roll 33 rotatably mounted in the casing I8, and as will be noted the side edges of the screen enter the chambers 24 through narrow passages in their adjacent sides.

Attached to the blocks 28 are chains 35' reaching downwardly and coiled around the ends of the roll 33 in such manner that the bar 21 is held in constant tension irrespective of the screen 32, as the roll 33 has mounted in it aspindle 3l actuated by a coiled spring 35"and tensioned by an extending lug 35, the device being in fact a modification of the well known curtain roll. 25

As shown in Figure 10, the screen device may be applied at the top of the window, as well as at the bottom, and it will be understood that the Vscreen roll structure whenonce appliedcan remain inv position indeilnitelyl and obviously is raised andlowered with the sash.

Although the improvements have been described with considerable detail and with respect to certain particular forms of the invention, it is not desired to be limited to such details since many changes and modications may well be made without departing from the. spirit and scope of the invention in its broadest aspect'.

Having thus described vthe inventio claimed as newand desired to secure by Patent, isz-,-

1. In a screen for windows having slidable sashes, a- ,casing xed on the sill of said window, chambered uprights communicating with said casing at its ends, across bar extending between said uprights and movabletherein said bar,hav ing guide blocks at its ends, clips on said' bai` adapted to engage' one of said sashes, a spring actuated rollv revoluble in said casing, a screen s having itsside edges slidable within said uprights, 50 said screen being fixed at its` upper end to s'aid v bar and at its lower endto said roll, and flexible connections between said blocks and said roll to relieveY the screen from tension.

2. In a screen for windows having slidable what is lictteis 40 5 blocks at its lateral ends movable in said uprishts.

a screen having its edges extending ,into said uprights, said screen being xed at its upper edge.
